Chemical Properties:colourless liquid
General Description:A clear liquid, essentially odorless. Closed cup flash point 192°F. Vapors are heavier than air. Contact with the skin may cause stinging and burning and lead to an odor of garlic on the breath. An excellent solvent that can transport toxic solutes through the skin. High vapor concentrations may cause headache, dizziness, and sedation.
Reactivity Profile:Dimethyl sulfoxide decomposes violently on contact with many acyl halides, aryl halides and related compounds such as phenyl and tolyl chloride, acetyl chloride, benzenesulfonyl chloride, benzoyl chloride, cyanuric chloride, phosphorus chloride, phosphorus oxychloride, and thionyl chloride [Chem. Eng. News 35(9):87 (1957)]. Reacts, possibly violently, with iodine pentafluoride [Chem. Eng. News 47(12):, 109(1969)]. Vacuum distillation from anhydrous magnesium perchlorate led to an explosion [MCA Case History 1187(1966)]. Violently reactive with fluorinating agents such as silver fluoride [Chem. Eng. News 44(24):7(1956)]. Can explode with sodium hydride [Chem. Eng. News 44(24):7(1966)]. Mixture with methyl bromide resulted in an explosion that shattered the apparatus [NFPA 491M, 1991]. Forms salts with perchloric acid that are explosive when dry [Chem. Abst. 44:p3935d (1950)]. Decomposes when heated above normal boiling point.
Health Hazard:Slight eye irritation.
Fire Hazard:Special Hazards of Combustion Products: Sulfur dioxide, formaldehyde, and methyl mercaptan can form
